Just need the answer. in degrees thanks;)

1. QR = 36 ; PR = 45 ; PQ = 21, Sin _?. = 21 / 45

2. QR = 16 ; PR = 2 ; PQ = 8, tan _?_ = 8/16

3. QR = 15; PR = 28 ; PQ = 15, Cos _?_= 15 / 28

4. OR = 47 ; PR = 64 ; PQ = 38, tan_?_= 38 / 47

5. OR = 4 ; PR = 17; PQ = 12, Sin _?_1 = 12 / 17

6. OR = 36 ; PR = 59 ; PO = 20, Cos __?_= 36 / 59

7. OR = 82 ; PR = 63 ; PQ = 29, tan __?_= 29 / 82

8. QR = 10 ; PR = 28 ; PQ = 8, Sin _ ? 11 = 8 / 28

9. QR = 51 ; PR = 42 ; PQ = 9, tan _?__ = 9 / 51

10. OR = 16 ; PR = 20 ; PQ = 17, Cos __?_|| = 16 / 20

11. QR = 12 ; PR = 84 ; PQ = 60, Sin? = 60 / 84

12. OR = 19 ; PR = 32 ; PQ = 45, Cos _ ? = 19 / 32

13. QR = 76 ; PR = 27 ; PQ = 64, tan __?_= 64 / 76

14. OR = 26; PR = 48 ; PQ = 37, Cos __?_= 37 / 48

15. OR = 19 ; PR = 66 ; PO = 23, Cos_?_= 23 / 66
